An integrated electronic device includes a substrate, passive components, pads for external connection, and three-dimensional wiring. The passive components includes a multi-stage coil inductor provided on the substrate. The multi-stage coil inductor has a plurality of coils disposed in several layers. Mutually adjacent coil wires are spaced-apart from each other. The three-dimensional wiring includes a first wiring portion which extends on the substrate, a second wiring portion which extends off the substrate but along the substrate, and a third wiring portion connecting with the first wiring portion and the second wiring portion.

The present invention relates to a frame communication system composed of a code converter and a frame generator/decomposer. In order to improve a line efficiency without encapsulating transmitting data, a code converter in a frame transmitting device converts at least different specific codes X and Y within the transmitting data respectively into codes (Y, A) and (Y, B) composed of the code Y and at least specific codes A and B different from each other, and a frame generator prepares a frame of the transmitting data with the code X as a frame boundary. A frame decomposer in a frame receiving device recognizes a specific code X as a frame boundary to decompose receiving data, and a code converter converts codes (Y, A) and (Y, B) within the receiving data composed of a specific code Y, and specific codes A and B into codes X and Y.

An objective lens system includes a first lens and a second lens. The first lens has a first surface for allowing entry of light and a second surface opposite to the first surface. The second lens has a spherical third surface and a flat fourth surface opposite to the third surface. The third surface faces the second surface and has a radius of curvature r0. The second lens has a thickness d0 and a refractive index n0. The thickness n0, the radius of curvature r0 and the refractive index n0 satisfy a relation: d0>r0>n0d0.

The high purity C/C composite formed by graphitizing a molded member packed with carbon fibers and carbon material of a matrix. The carbon fibers are high purified under halogen gas atmosphere. The purified carbon fibers are molded into the desired shape on a tool or in die with infiltrating the matrix. The molded member packed with carbon fibers and carbon material of the matrix are either independently or simultaneously graphitized and then high-purification under halogen gas atmosphere. According to the present process, the metal impurities can be very low contents.

An ultrasonic actuator to suppress or eliminate pitching vibration arising in a vibration element when driving the ultrasonic actuator and to increase driving efficiency and reduce noise. The ultrasonic actuator includes a vibration element; an electromechanical conversion element mounted on the vibration element to generate a drive force in the vibration element by excitation of the electromechanical conversion element; drive force output members to extract a drive force obtained by excitation of the electromechanical conversion element; a relative motion member in contact with the drive force output members and driven in relative motion with respect to the vibration element by the drive force; a base member; and a fixed member to fix the vibration element to the base member. The vibration element generates, by excitation of the electromechanical conversion element, a first vibration in a first direction, and a second vibration in a second direction different from the first direction, and the fixed member is located in at least two (2) positions along the vibration direction of the first vibration and includes a first restriction member to restrict the vibration element in a vibration direction of the first vibration, and a second restriction member to restrict the vibration element in a vibration direction of the second vibration.

摘要:
A vibration actuator drive device using a linear type of ultrasonic actuator to drive a rotary member with high accuracy and good efficiency. The vibration actuator drive device includes an ultrasonic actuator which, by applying drive signals, produces longitudinal vibration and bending vibration to generate a drive force, and a rotary member in contact with the ultrasonic actuator. The combination of longitudinal vibration and bending vibration in the ultrasonic actuator generates relative motion in the rotary member having a circular locus of predetermined width. A compression mechanism causes compressive contact of the ultrasonic actuator with the rotary member. The longitudinal vibration vibrates in a direction about parallel to the direction of the drive force, and the bending vibration vibrates in a direction intersecting the longitudinal vibration. A drive force is transmitted to the rotary member at the inner circumferential side of the circular locus, and greatly differs from the drive force which is transmitted to the rotary member at the outer circumferential side. A lens barrel including a vibration actuator drive device drives a focus adjustment lens group in the optical axis direction by the conversion of the rotary motion of the rotary member to linear motion.
